SPECIFICATION forming part of Letters Patent No. 465,900, dated December29, 1891.

Application filed October 13, 1891. Serial No. 408,620. (No model.)

To all whom it may concern.-

Be it known that I, ORLANDO OWEN WALK- ER, a citizen of the UnitedStates, residing at Redford, in the county of Taylor and State of Iowa,have invented a new and useful (lave,

of which the following is a specification.

This invention relates to a subterraneous cave; and the objects in vieware to provide a cheap simple water-tight subterraneous IO cave adaptedto be easily set up and taken down with safety and without impairmentand to serve as a receptacle for perishable articles and also as aretreat for persons during cyclones, floods, &c.

I 5 Other objects and advantages of the invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the claims.

Referring to the drawings, Figure l is a perspective of a caveconstructed in accord ance with my invention. Fig. 2 is a verticalsection thereBf. Fig. 3 is a detail of one of the roof sections. Fig. 4is a detail of the roof-key. Fig. 5 is a detail of one of the sidesections. Fig. (3 is a horizontal section of the cave.

Like numerals of reference indicate like parts in all the figures of thedrawings.

In forming the wall of the cave I employa series of tile-sections 1,which are curved in cross-section, provided at one of their longitudinaledges and upon their outer sides or faces with flanges 2, and at theirupper ends and upon their outer faces with curved flanges 3. A series ofthese ties assembled so that the flanges 2 will overlap the adjacentedges of the adjacent tiles are cemented together along their meetingedges and constitute an annular Wall. This wall is provided at a pointdesired with an opening 4, and is mounted, preferably, upon a suitablemasonry of brick and cement, or cement alone, so that the joints betweenthe bottoms of the tiles and the tiles themselves are impervious to 5moisture. The roof is semi-globularor arched,

and consists of a central circular key 5, having a central perforation Gand an annular peripheral groove 7, and in a series of tapered orV-shaped curved roofsections 8, adapted at their inner ends to take intoand fit the annular recess 7 and at their outer ends to rest upon theupper ends of the wall-sections 1 and to be surrounded by the annularflange 3 of said wall. The roof-sections 8 are pro vided at one sidewith overlapping flanges 9, which overlap the joint between itself andthe adjacent section, in which positions the series of sections arecemented. A ventilat ing-pipe 10 passes upwardly through the circularkey 6 and may extend any height.

That one of the sections 1 located at each side of the doorway isprovided at opposite sides of the doorway with flanges 10 at a rightangle to the remainder of the section, and extending some distance belowthe same and above the edge of the roof,and in rear of the same a fender11 is located and supported by the roof, said fender being designed toprevent rocks and dirt from falling from the roof into the doorway.

A pair of vertical walls extend from the doorway and have their upperedges inclined and their outer edges connected by a transverse wall.These Walls are composed of a series of tile-sections 12, and the samehave their upper edges channeled, as at 13, while one edge of eachsection has an overlapping flange 11. The recesses 13 of the tilesreceive a sectional door 15, also having an overlapping flange at itscenter. All of the joints are cemented, and hence the structure isabsolutely Water-proof. Ventilation is afforded to the ventilating-pipedescribed.

In cold weather the cave, being located below the ground, will serve asa convenient storage-place for edibles, which will be pre vented fromfreezing, and in warm Weather it may be used for a similar purpose forpreventing decay. During cyclones, floods, high winds, &c., it serves asan excellent retreat for the safety of persons and prevents harm frombefalling them.

It will be seen that the device may be set up and taken down with verylittle trouble and may be transported from one place to another withoutdanger of breakage or the incurrence of much expense.

Ilaving described my invention, what I claim is 1. In a cave of theclass described, the combination, with the annular wall having a recessin its upper edge, of a dome formed of sections tapered and curved, eachof said SOC tions being provided at one edge with an overlapping flange,the outer ends of the sections resting upon the wall, and a circular keyhaving a peripheral recess for the reception of the inner ends of thesect ions, substantially as specified.

2. Ina cave of the class described, the combination, with the annularwall formed of tiles and provided with an opening, of a dome mountedupon the wall and formed of tiles, the tiles at opposite sides of theopening: he-

iug provided with flanges extending above the opening, a door for theopening, and a shield supported upon the root in rear of the flanges,substantially as specified.

3. In a cave of the class deserihed,'the combination, with the annularwall formed of tiles and provided with an opening and the dome, the tileat each side of the opening being provided with an outwardly-disposedflange, ol' inclined vertical walls cemented to the flanges and providedat their upper and outer edges with recesses, a transverse Wall mountedin the recesses at the outer ends and provided with overlapping flanges,and a door formed of tile'seetions, the opposite edges of which rest inthe recesses in the upper ends of the vertical walls, the inner edge ofone of said doorsections having an overlapping flange, substantially asspecified.

In testimony that I claim the foregoing as my own I have hereto alfixedmy signature in the presence of two witnesses.
